SUMMARY 

One of the basic requirements for high yield and high quality potatoes 
is good insect control. This in turn necessitates an understanding of 
the crop environment and more particularly of the arthropod community. 
This technical bulletin contains a complete list of the more than 565 
different species of arthropods collected in a survey of New Brunswick 
potato fields carried on between 1979 and 1981. The total yearly catches 
of each species or group-species and the seasonal abundance of common or 
important groups are presented in tabular form. It will provide 
extension specialists, entomologists and quarantine officers with a 
checklist of insect species that can be found on potatoes and data on the 
relative abundance and seasonality of these arthropods. 



Resume 

Pour obtenir des pommes de terre de haute qualite et un rendement eleve 
il faut, entre autres, bien controler les insectes nuisibles. Ceci 
requiert une bonne comprehension du milieu de culture et plus 
parti culierement de la communaute arthropodienne. Ce bulletin technique 
contient une liste complete des quelques 565 differentes especes 
d'arthropodes receuillies lors d'un inventaire des champs de pomme de 
terre du Nouveau-brunswick realise de 1979 a 1981. Les captures annuelles 
totales de chaque espece ou groupe d'especes et l'abondance saisonniere 
des groupes communs ou importants sont presentees sous forme de 
tableaux. Ce bulletin fournira aux specialistes de 1'extension, aux 
entomologistes et aux officiers en charge de la quarantaine une liste de 
controle des especes d' insectes susceptibles de se trouver sur pommes de 
terre et des donnees sur l'abondance relative et saisonniere de ces 
arthropodes. 



INTRODUCTION 

The potato is a solanaceous plant which originated from the Andes 
in Peru. Introduced in Canada in 1623, it is now planted in 108,300 ha 
of which 22,000 are in New Brunswick (CIP 1980, NBDA 1981). Due to the 
importance of export markets--36% of the province's total production 
(New Brunswick Department of Agriculture 1981)--particularly high 
standards Of seed quality have been set for New Brunswick potatoes. 

One of the basic requirements for high yield and high quality 
potatoes is good insect control. Insect pests are well known (Hodgson 
et al. 1974, MacGillivray 1979 a, b, Radcliffe 1982) but the rest of the 
arthropod community has never been fully surveyed (Shands and Landis 1964, 
Shands et al . 1965, 1972). It is important to know the entire fauna 
because all species are linked together by their effects on one another 
and the environment they share. Insect control methods do not affect only 
the target species but all the other ones that depend on it or simply 
inhabit the same immediate space. 

A faunal survey of New Brunswick potato fields was carried out 
during the 1979, 1980 and 1981 growing seasons and has identified more 
than 565 different species or group species from the more than 477,150 
specimens collected. To our knowledge this is the first comprehensive 
survey of arthropods in potato fields in North America. This bulletin 
provides a complete listing of the species collected each year. In a 
second part, the seasonal abundance of important or common arthropods 
(generally at the family level) is presented in a tabular form for each 
sampling method. Four sampling procedures were used to get as complete 
a picture as possible of the whole community, gather some information on 
their habitat preference (e.g. foliage or ground species) and their ability 
to disperse by flight (yellow water pan catches). The structure of the 
community has been described elsewhere (Boiteau 1983). 

Specimens of each taxon are maintained in the potato reference 
collection at the Fredericton Research Station. 



MATERIALS AND METHODS 

Except for Charlotte, Saint John and Albert, all counties of New 
Brunswick were surveyed in the 1979 and 1980 growing seasons. In 1981 
the survey was limited to the major potato growing areas of Carleton, 
Victoria and Madawaska. All fields belonged to growers participating in 
the New Brunswick potato pest management program. Some fields were 
insecticide' free but most received between 1 and 6 spray applications. 
This was not considered detrimental, but on the contrary, an integral 
part of the artificial environment of the potato field. Fields were 
sampled by sweepnet, ground cloth, pitfall traps and yellow water pans. 

Sweepnet samples were taken from a 60 x 60 m area approximately 
60 m from the edge of each field. A scout walked between 2 rows swinging 
a 38 cm diam sweepnet upward alternatively on each row synchronized with 
successive steps. Four sets of 50 sweeps randomly selected were taken in 
each field. Samples were taken weekly from the time plants reached 
38 cms to top kill or the end of August. Forty three, 45 and 6 fields 
were sampled in 1979, 1980 and 1981 respectively. 

The location and timing of ground cloth samples were similar to 
those used in the sweepnet procedure. A 1 meter square cloth was unfolded 
between 2 rows and about 2 m of foliage from each side vigorously shaken 
over the cloth. Four samples were collected randomly in each of 43, 35 
and 6 fields in 1979, 1980 and 1981 respectively. 

Pitfall traps consisted of a 0.5 L plastic cup (31 cm perimeter, 
12 cm depth) sunk into the top of the row and 1/3 filled with a 50% 
solution of ethylene glycol and water as preservative. A 15 x 15 cm 
aluminum shade cover mounted on 15 cm nails was positioned approximately 
5 cms above the cup to protect its contents from precipitation. Traps 
were emptied once a week from the time of planting to the end of August. 
Ten to twenty traps were placed in each of 21, 16 and 7 fields in 1979, 
1980 and 1981 respectively. 

Yellow water pans measured 35 x 47 cm. Two pans were located in the 
center of a 60 x 60 m area adjacent to the access road but halfway 
between the sidelines of each field. The first trap was 15 m from the 
edge and the second one 30 m further on the same row. Traps were 
eniDtied twice a week. Traps were operated in 51 fields in 1979, 51 in 
1980 and 9 in 1981. 

All samples were brought back to the laboratory for identification 
and counting. Collections were sorted into morpho-species which were 
pinned and assigned a reference number. Representative specimens of 
e\/ery putative species were then submitted to specialists at the Agriculture 
Canada Biosystematic Research Institute, Ottawa, for identification. 



ARTHROPODS ASSOCIATED WITH POTATOES 



This list contains all of the arthropod species or group-species 
collected in potato fields throughout the province of New Brunswick during 
three successive years. The list is arranged according to the classification 
of Borror et al. (1976) except for the families and genera that are 
arranged alphabetically. The total number of specimens collected is given 
for each taxon and each year.

SEASONAL ABUNDANCE OF ARTHROPODS 

The following table contains data on the seasonal abundance of 
selected groups of potato arthropods for 1979, 1980 and 1981 and for 
each sampling method. Years when groups were present in less than five 
sampling dates have not been included. Figures refer to the average 
number of arthropods per pitfall trap, yellow water pan, 50 sweeps or 
one ground cloth in positive samples. The number of positive samples 
(number of fields with at least one arthropod) is given in brackets. 
Sampling started around the first of June and ended at topkill or in 
September.
